So you're aware, Collide will be releasing an updated version on his Patreon in the next month that adds floors 5 and 6. This will include a shared CG gallery; some ~30 additional days for interactions; new hideout and exploration events; and routes for 8 characters (Pierce, Mage, and Victor, plus 5 new characters).
And yes, the Mage is currently bugged in both the free and Patreon versions.
